Money Birute deposited in a savings account = $500
Rate of simple interest per annum = 1.3%
▪︎We need to find the interest she will earn in 4 years.
We know that :

In this case :
Principal = $500
Rate = 1.3%
Time = 4 years
Which means :
The simple interest she will earn in 4 years :



Thus, the simple interest she will earn in 4 years = $26
Amount = Principal + Interest
Amount she will gain after 4 years :


Thus, the amount she will gain after 4 years = $526
Amount change in her account = 526 - 500 = 26
We know that :

Which means :
Percentage of change in her savings account :




<h2>○=> Therefore :</h2>
▪︎Simple interest after 4 years = $26
▪︎Money she will earn after 4 years = $526
▪︎Percentage of change in her savings account = 5.2%
8 weeks
First, find how much money Maurisa saves each week. 25% is the same as 1/4, and 1/4 of 8 is 2, so Maurisa saves $2 each week.
Finally, just divide $16 by $2 per week to find that Maurisa will take 8 weeks to save $16.
Answer: When they work 10 hours each, they both make $300.
kelli y = 20x + 100
karl y = 25x + 50
substitution:
y = 20x + 100
25x + 50 = 20x + 100
-20x -50 -20x -50
--------------------------------
5x = <span>50
</span>5 5
x = 10
(Then plug into any equation)
y = 25x + 50
y = 25(10) + 50
y = 300
When they work 10 hours each, they both make $300.
